To aZZ whom it petty concern:

Be it known that I, Jonn Sronns, a citizen of the United States, and a resident of Clyde, in the county of Walla Walla and State of Washington, have invented an Improved Plow Attachment, of which the following is a specification.

In many agricultural localities wheat or other grain 1s headed in harvesting, thus leaving lon straw or stubble which clo s the plow in suisequent fall and siring cu tivation, so that the plowinen fin it necessary to make frequent halts in order to remove the straw or stubble, so as to continue to do effective work.

I have devised an improved plow attachment for ressing down or flattening wheatstraw stulible or gross on the furrow-slice as turned by the plow. To this end I rovide a, ribbed roller which is hold rotatalily on s. swinging srrn journeled on the plowbeam, the roller being adapted to work at such angle and in such proximity to the moldboerd of the plow that it acts on the furrow-slice at its turningioint, so as to break, press down, or fist-ten t 1e straw, stubble, or grass in such manner that it is buried in the furrow beneath the slice.

The details of construction, arrangement, and operation of my improved attachment are as hereinafter described, and illustrsted in the sccoinpanying drawings, in which Figure 1 is a side view of a plow provided with my iln roved attachment. Fig. 2 is a plan view 0 the same. Fig. 3 is a vertical transverse section on the line 3 3 of Fi 2. Fig. 4 is a central longitudinal section 01 the straw or stubble roller. Fig. 5 is a side view showing the roller in the position it occupies when at work.

A hollow iron or other mounted rotatably upon the journal 1, formed by the lower end of an angular arm B, whose upper horizontal portion 2 is journaled in a. bearing 3, that rests upon and is clamped to the plow-beam 4 at a point almost directly over the share or point 5 of the plow. The said roller is ribbed longitudinally or, in other words, provided with a series of lengthwise ribs 6, which are thickened or extended radially at their inner ends 6 for a, purpose that will be presentl explained. The roller is constructed hollow for sake of convenience and economy of manufactures A suitable bearing 7 may be provided, as shown in Fig. l, the bent portion or journal of arm B passing metal roller A is the straw or stubble or,

through the elongated bearing' snd having a. nut applied to its inner end, whereby the roller is secured to the 'ournsl dctachahly. The rollerbearing may e constructed integrelly or with spokes forming the outer end of the some. The arm 13 has four principal bonds or angles at its up or end 8, (see Fig. 3,) being bent downward and curved at its extremity, as indicated in Fig. 1, thus forms ing a lever member to which a spiral spring 9 is attached, the opposite end of the spiral being secured to a. collar 8., The rollerournal I, and consequently the roller itself, is placed at on inclination of sixty degrees with the moldboard or inclined side of the plow proper, so that it may correspond to the inclination of furrow-slice as it passes up over theshare or moldboard end is turned thcreby, so as to lie inverted in the furrow provionsly made. The pressure of the roller against the furrow-slice tends to force it backward, which movement is resisted by the spiral 9 to a degree corresponding to its stren th or tension.

In igs. 1, 2, and 3 the roller is shown in the forward position thst is to ssy, in the position it assumes when the spiral 9 is contractedand Fig. 5 shows the position it assumes when forced rearward, the spiral being in such case expanded more or less. The ribs or teeth of the hollow roller A cause it to take a firm hold on the hirrow-slice and also aid in breaking down the straw or stubble thereon. The radial projection 6 of the ribs enables it to prevent lateral escape of the straw or stubble to a renter degree than is practicable with ribs o unilorrn thickness or eight. In other words, such projection 6 revents the straw or stubble slipping out aterall Tell} the roller at the end nearest From Fig. 2 it will be seen that the transverse horizon'tal portion 2 of the srinB, which constitutes the upper arm, is arranged at on inclination to the plow beam or, in other words, crosses at a suitable anglc say thirty degrees. Such angular arrangement of the journal 2 and the inclination of the roller A enable the letter to swing upward away from the hears, so that it cannotcome in contact with the letter when in operation.

The bar C (see Figs. 1 3, and 5) is attached to the beam 4 just in rear of the journal-bearing 3 and projects downward end forward. It is sdspted to serve as a guard for catching in other words, as-

sisting in turning the straw or stubble downward laterally, so that it will be caught by and share to adapt it to work on the outer side of the lurrow-shce, and a retracting the roller A and more effectively broken l spring attached to the dew-beam and condown and flattened. The guard C may be secured by a clam or slotted to receive a clamping-bolt. W ien the plow and its attachment are in use, the roller is pressed back behind the guard C, as shown in Fig. 5 5 but, as indicated in other figures, the roller is held normally in front of the guard when not in use. When traveling to or from the field, the spring is unhooked and. the roller A turned up on top of the plow-beam.

It will be seen that by the construction and combination of parts hereinafter described I reduce an attachment for rolling down and flattening straw and stubble in plowing which is adapted for application to plows in general; further, that the attachment may be easily a plied and removed and is in itself simple an inexpensive and very effective in operation. When applied to gang-plows, it may be fastened to a cross-brace extending between and connecting the beams.

What I claim is 1. The combination, with a plow of an attachment for rolling down straw and stubble, the same comprising a roller having longitudinal ribs, an angular arm journaled upon the plow-beam and pendent therefrom, the roller being arranged at an angle to a beam nccted with a lever member of said arm, whereby it tends to resist rearward movement of the roller when acting on. the furrowsliee, substantially as described.

2. The combination, with a )low, of the attachment comprising a roller or acting on a furrow-slice, an angular arm on whose longer pendent member the said roller is mounted, the arm being journaled 0n the plow-beam and its shorter member being pendent on the side of the beam opposite the roller, and a spiral retracting spring attached to such shorter member and to a forward portion of the plow-beam, as and for the purpose specified.

3. The combination, with a plow, a straw and stubble roller, a swinging arm upon which it is mounted rotatably and a contractible spring, of a guard consisting of a bar attached to the beam and projecting downward adjacent to the inner end of the roller, whereby it is adapted to aid in turning straw and stubble on the furrowslice, substantially as described.
